Granted: 2000-05-16
Abstract: A needle shield assembly having a single-use cannula lock of the present invention includes a needle cannula having a proximal end, a distal end and a lumen therethrough. A hub includes a proximal end for connection to a fluid transfer device and a distal end connected to the proximal end of the needle cannula. A collar is rotationally connected to the hub so that the collar can be rotated around the hub. An elongate needle cover removably engages the hub and covers the needle cannula.  An elongate needle shield having a proximal end and a distal end is hingedly connected, through its proximal end, to the collar. The needle shield includes two sidewalls defining a longitudinal opening and a back wall between said side walls defining a recess having an interior surface. The needle shield is capable of pivoting from an open position wherein the needle cannula is exposed, to a closed needle protecting position wherein at least part of the needle cannula is within the longitudinal opening of the needle shield. The needle shield assembly further includes structure for preventing the needle shield from pivoting into the closed position unless the needle cover is removed, and structure for locking the needle shield in the closed needle protecting position when the needle shield is pivoted into the closed position. The structure for locking traps the needle cannula in the longitudinal opening of the needle shield.

Title: Structure en beton ayant un element d'insertion pour transferer des charges et procede de realisation
Inventor: KELLY DAVID L
IPC: E04B1/41

Abstract: Un élément de support pour une structure en béton comprend une pièce d'insertion (10) en forme de T délimitant un volume interne (14) en forme de T. Un écrou (20) est inséré dans la portion transversale du volume interne et des capuchons d'extrémité (24) sont placés sur les extrémités de la pièce d'insertion pour fermer et isoler complètement le volume interne. La pièce d'insertion est alors placée dans un coffrage pour une structure en béton de manière à ce que la surface de base de la pièce d'insertion en forme de T soit coplanaire par rapport à une surface du béton, après que le béton a été versé dans le coffrage et qu'il a pris. La paroi de base (12a) de la pièce d'insertion est ensuite enlevée, ce qui laisse ouvert le volume en forme de T. L'extrémité distale d'un boulon (2) peut être insérée dans la pièce d'insertion et fixée à l'écrou (20). L'extrémité proximale du boulon fait saillie hors de la pièce d'insertion et au-delà de la surface du béton et elle peut servir pour la fixation d'une pièce d'équipement ou d'une autre structure qui doit être supportée par la structure en béton. On peut prévoir des pattes (42) sur les capuchons d'extrémité pour tenir la pièce d'insertion à distance de la surface du coffrage pour que, lorsque le béton est versé et qu'il a pris, la pièce d'insertion se trouve noyée dans le béton plutôt que jouxtant la surface du béton. On peut prévoir des antennes (44) sur les capuchons d'extrémité faisant saillie au-dessus de la surface de base de la pièce d'insertion en forme de T pour que ces antennes fassent saillie au-dessus de la surface du béton, de façon à ce que la pièce d'insertion puisse être facilement localisée visuellement.

Abstract: A one-piece shot cup (also commonly known as a shot pouch) designed especially for use in protecting the bore of a shotgun barrel when shooting hard shot made of a material such as tungsten or non-annealed steel. The cup is characterized by the use of shield members located opposite and outwardly of equally spaced tear lines which are defined by narrow areas of substantially weakened wall structure extending longitudinally of the cup. The shield members are connected to the wall structure of the tubular members only adjacent its closed rear end portion and are otherwise separate and free thereof.      Portions of the tubular members extend between the circumferentially spaced shield members. The shield members prevent the shot, which ruptures the tear lines, from damaging the bore of the shotgun barrel. They also aid in holding the shot in an improved aligned relation to thereby improve the shot pattern. They also aid in causing the shot cup to separate from the shot immediately after leaving the end of the barrel of the gun. The tapered wall thickness of the pouch is within the range of 0.060" at its front end and 0.080" at the rear end of the pouch.

Abstract: A method and apparatus for looking up a key associated with a packet to determine a route through a routing device, the method including, upon receipt of a key, forward traversing one or more nodes which make up a trie stored in a memory by evaluating at each node traversed a bit in the key as indicated by a bit-to-test indicator associated with each node. A value of the bit in the key determining the path traversed along the trie. The method includes locating an end node having a route and comparing the route to the key (528).  If they match, destination information associated with the end node is outputted to guide the transfer of the packet through the routing device (529). If they do not match, the trie is traversed backwards to locate a best match for the key.
